Shares in US chipmaker Skyworks Solutions came under pressure on Friday after KeyBanc Capital Markets downgraded the stock, citing growing headwinds in the global smartphone market. The investment bank lowered its rating from Overweight to Sector Weight, pointing to softening demand for mobile handsets, especially in China, a key market for Skyworks' radio-frequency components.
The downgrade, issued late on 17 July, sent Skyworks shares down more than 3% in after-hours trading. The stock had already fallen around 12% year-to-date amid a broader sell-off in semiconductor equities. KeyBanc analysts said they see limited upside for Skyworks in the near term given inventory build-ups and weaker consumer spending on premium smartphones.
The ripple effects were felt across the Atlantic, where UK-listed semiconductor and technology stocks edged lower in early trading on Friday. Shares in IQE, the Cardiff-based wafer supplier, fell 1.8%, while ARM Holdings, which is listed in New York but has significant UK operations, saw its stock dip in pre-market activity. The FTSE 100 was broadly flat, but the technology sector underperformed, with the FTSE 350 Technology Index slipping 0.4%.
Analysts at Peel Hunt noted that the downgrade reflects a broader caution in the semiconductor space. 'Skyworks is a bellwether for the smartphone supply chain,' said a note from the broker. 'If demand weakens further, UK component suppliers and foundries could face margin pressure in the second half of the year.' The warning comes as investors already grapple with elevated interest rates and subdued consumer demand across Asia.
For UK pension holders and retail investors, the development underscores the vulnerability of global tech stocks to shifts in consumer electronics cycles. Many UK pension funds hold exposure to US semiconductor names through index trackers, and a sustained downturn in smartphone sales could weigh on returns. The Bank of England is expected to keep a close watch on corporate earnings in the sector as it assesses the health of the global economy.
